Merged Smash and Gore to be on the same HUD slot: the correct attack will automatically be chosen depending on your target.

Gorges can now build Clogs! These are Minecraftian style building blocks of infestation that they can use to wall off areas or protect structures.

Gorges no longer pay resources to build anything, but instead have a set limit of each type of structure they can build. They get more with each additional hive.

Reworked Drifters. They no longer build structures - instead, the Commander can build structures directly out of the infestation. Soon, Drifters will given more support type abilities (thanks WorthyRival!). Read more here.

Added spike tracer effect (so you can see projectiles) for Lerk and Hydras.

Added Drifter Camouflage (when still, they fade away but provide line of sight).

Added new Cloak/Camouflage effect.

Balance

Reduced Lerk max speed by -15% (now 11...sorry SabaHell!).

Bumped up emergency spawn threshold from 4 to 5 players.

Further weakened Harvesters when they are built. Increased Harvester build time to 60. Watch out, they are very weak to start.

Lowered initial Hydra health and armor, and it now takes 2 minutes for Hydras to mature.

Hardly any teamwork , thus the 80/20 percentage . You also don't need to win all the time to have fun , I'd be happier if I lost a match where me and my team played cooperatively and gave the aliens a hard time :) .
About the fixing thing that you said : I think it's fine now , balancing a game of this calibre isn't easy at all , and I mean it. Expect loads of patches even after release ; it's a normal thing , look at other games especially team-focused ones .
It depends on what you want from a game , I personally want to have a blast .

Oh I know, I expect patches post release and all that, a continual effort to balance.

But I'm talking about alot of things just don't seem like they'll be ready for a release this year...unless they release without them and patch them in later, something not everyone is a fan of.

Aliens actually need the least Teamwork, unless that's what you mean. Marines require building structures and moving about in groups of 2-3 to be anywhere near effective.

But a Single Alien, due to the hitbox issues at current can kite around and kill all 3, even if you used a aim bot due to the melee hit detection. It's gotten better in patches, especially after the devs removed lag compensation for the Aliens. (Pretty much meant you could see your entire clip unload into them and not do any damage)

And yes, it's not about winning, but the issue here is, without a Commander, Aliens can still function to mostly their full potential.

But Marines, without a Commander, or a good one, are completely screwed.

Most games turn out with Aliens rushing and winning, because they can do it due to their unique mechanics, or Aliens rushing, badly damaging the base, leaving Marines spending all their time getting the base back up to par, then the Aliens have had time to actually do stuff.

Marines are having a hard time holding resource nodes, I noticed the games that Marines win on are when Aliens fail to keep on top of taking down Marine resource nodes.
I also see that the Aliens can branch out a lot faster than marines with the recent changes to the way Alien Command now works not having Drifters required to build means they are not waiting for it to not only reach it's destination but also survive it's journey as previously killing one destined for a node was a setback for the Aliens and a Push for the Marines.
Making Alien Command simpler to use has obviously had a drastic affect on balance and now requires to be addressed and will be addressed soon.
